1 Claim.

1 r The invention aims to provide an exceptionally simple and inexpensive, yet a practicable and desirable amusement device in which a seesaw I is mounted for both oscillation and rotation, and in which the motions caused by the children in seesawing, will produce the rotary motion.

With the foregoing in view, the invention resides in the novel subject matter hereinafter I described and claimed, description being accomplished by reference to the accompanying drawings.

Figure 1 is a side elevation.

Fig. 2 is a top plan view.

Fig. 3 is an enlarged vertical sectional view partly in elevation, as indicated by line 3--3 of Fig. 1.

A preferred construction has been illustrated and will be specifically described, with the understanding, however, that within the scope of the invention as claimed, variations may be made.

A suitable base 5 is provided, said base preferably comprising upper and lower crossed boards 6 and '1, blocks 8 secured under the ends of the upper board 6 and additional blocks 9 secured on the ends of the lower board.

A central post 10 is rigidly secured to the base 5 and is braced by a plurality of brace bars II which are spaced about said post, said brace bars being inclined, having their lower ends secured at l2 to the base, and having their upper ends secured l3 to the post, near the upper end of the latter. Upwardly diverging track-supporting bars l4 cross the brace bars II and are secured at l5 thereto, the lower ends of said track-supporting bars being secured at IE to the lower end of the post I0. The upper extremities of the bars M are disposed in an inclined plane and are formed with upwardly open notches [1. A circular track [8 is provided with a downwardly projecting flange l9 received in the notches H, said flange being secured to the bars H by bolts or the like 20. The circular track [8 is-thus rigidly mounted in an inclined plane.

Above the post l0 and track [8, is a seesaw 21 which is mounted for vertical oscillation and for rotation about a vertical axis, upon the upper end of said post l0. Between its mounting means and its ends, the seesaw 2| is provided with two rollers 22 which rest upon the track l8 at diametrically opposite sides, said rollers being 2 mounted on axes extending longitudinally of said seesaw. Thus, the seesaw 2| may both rotate and oscillate simultaneously, and children using it will soon accustom their movements to the action of the device so that they may not only seesaw but may cause a merry-go-round movement at the same time. Each revolution of the seesaw causes one descent and one ascent of one end of said seesaw, and the reverse for the other end, and these ascents and descents occur so smoothly that they do not interfere with free and rapid rotation and have no tendency to throw the children from the seats.

It is preferable to mount the seesaw on the post in the manner shown. The lower side of this seesaw is provided along its central portion with two spaced longitudinal cleats 23 secured thereto at 24. The centers of these cleats are formed with bearing sockets 25 which open inwardly and are alined transversely of the seesaw. These sockets receive the ends of a horizontal pivot cross bar or shaft 26, said shaft having a central vertical opening 21 through which a lag screw or the like 28 passes, said screw or the like being driven into the upper end of the post it). A washer 29 is interposed between the shaft 26 and the upper extremity of the post, and another washer 30 is preferably provided between said shaft and the head of the lag screw or the like 28.

Two transverse angle metal bars 3! are preferably provided upon which to mount the rollers 22, said bars 3| being secured at 32 to the seesaw 2i and having their ends disposed against the inner sides of the cleats 23, to brace the latter From the foregoing, taken in connection with the accompanying drawings, it will be seen that a novel and advantageous construction has been provided for attaining the desired end, and while preferences have been illustrated, attention is again invited to the possibility of making variations within the scope of the invention as claimed.

I claim:

An amusement device comprising a base, a central post secured to said base, a vertical lag screw in the top of said post, a cross bar on top of said post having cylindrical ends and a central opening to receive said lag screw, whereby said cross bar is pivotally mounted on the post, a seesaw disposed above said post, two laterally 3 spaced cleats secured to the lower side of said seesaw and having at their central portions transversely alined bearing sockets opening only through their inner sides, said sockets rotatably receiving said cylindrical ends of the cross bar whereby the seesaw is pivotally mounted on said cross bar, two transverse bars secured to the lower side of said seesaw and spaced in opposite directions from said cross bar, the ends of saidv transverse bar abutting the inner sides of said' REFERENCES CITED The following references are of record in the file of this patent:
